Dear List,

I am trying to generate a .cdf-file (that could be used for programs such as
dChip or aroma.affymetrix) from a cdf-package downloaded from the
Bioconductor homepage (which provides me an environment containing the probe
mappings)...
Is there a direct way to do this (let's say something like
"writeCdf("myChipcdf-package"))? If not, how can I generate a cdfheader and
a cdf-list used for the function "writeCdf" from the mappings in the
environment? (I got hands on a script that uses a flat-file as input for the
function, but I am having problems generating this flatfile from the R
environment).

Thanks a million for any help on this.

Best wishes,

Sam
